how fast does it charge an iPhone?

The same time as using the Apple charging adapter. Having a higher current capacity does not mean that the battery will charge any faster, the safe charging rate is set by the power management circuitry in the iPhone. Charging any battery too quickly leads to overheating and possibly a fire. The PowerGen 4.2 does charge two iPads simultaneously. I hope this helps.

Jon, To be honest I didn't look at the reviews till after I bought it. Which is dumb, my charger charges my iphone 5 from 0-100% and then some more it is really reliable, despite what others have said. I hope that helps.

Well I have an Iphone 5 and it charges in about 2 hours, from 5 % battery. Also, I have the Galaxy Note II, and it will charge very quickly, I have the extended battery on the Galaxy, and it will charge both phone complete and the backup reach only 50%.

I have an iphone 4s and it completely charges in about 2 hours. However, you can use the phone while it is charging.

will charge about 1 iphone full HP... (when iphone is idling without using, around 80% if using simultaneously)

If you have the regular USB cable then yes, it may take a bit... depends if you are placing the charger in full sun... then it's a breeze. Regular IPhone4s in about 30 min.

I use it to charge my iPad and iphone at the same time. It charges quicker that the apple supplied chargers. It will also charge a iPod mini.

Yes. It charges our iPhones and iPods. We have it plugged in. We are not using the batteries. It does not have to be turned on to charge them. Just plugged in. It charges quickly too. Faster than a computer and some adapters.

Not sure about those specific devices, but my iPad and iPhone charge rather fast. Especially the iPhone. If you use the 2A output port, its much faster when charging a phone as opposed to a tablet. But apparently it's less efficient if you're trying to maximize the usage of the Maxboost Electron's battery. If you're not in a rush, they recommend phone be charged on the 1A port and tablets on the 2A, but when you're in a rush and yo need to chafe your phone, use the 2A port and you'll get a fast charge. I'd say my iPhone 5 goes from 2% to 100% in less than one hour. The iPad takes much longer.

The USB ports have a combined voltage of 2.5 amps. So with one connected you get all 2.5. With two connected you get around 1.5 amps each. It will charge but not as quickly as with just one connected. The AC Outlet works independently. So I currently have an iphone, and an ipad connected to the usb ports and a bluetooth speaker recharging on the AC outlet. All 3 are charging, albeit slower then if fewer devices were connected. Short answer is YES.

Yes, almost as fast as the Apple chargers. The Amazon product description says "The USB Ports are Type A, 2.0 and feature a combined power of 3.6 amps." My iPad2 charger is 2.1 Amps. This charger will charge two iPads at 3.6A/2=1.8A each, almost as fast as the two Apple chargers would. Actually it's likely better than that as devices often request less than the full 2.1A charger capability during charge.

It has a micro and a regular USB port. The Micro port is for charging it and the USB port is to bring power to the device you are charging. In short, yes it will charge your Iphone.

It charge iPhone first. and when it full. charge case. it is done automatically. one pitfall is case charging take quite long time with 5V 1A adapter (iPhone charger). I recommend iPad charger (5V 2.1A). With that It takes 2~3 hours to charge iPhone and case full

Yes, it does charge an iPhone 5, 4S and various iPods we have but only when plugged in to power, not when running on batteries only. Although I never used it to fully charge an iPhone so I don't know whether it's significantly slower or faster than the stock charger.

750 milliAmps (0.75Amp). An iPhone or iPad mini charges best with 1A; regular iPad is best with 2.1A. This charger will not charge two Apple iOS devices at the same time.

I can charge my iPhone 4S about 5 times. Pretty fast It will do my iPad 2. But sloooow. Well made nice looking unit.

I haven't measured it with a meter, but my iPad charges as fast as using the standard 2.1 amp charger so I'd say it does. If you charge an iPhone or iPod it charges faster than a standard 1 amp charger? You don't have to worry about too many amps - the device will only draw the current it needs.
